摘　　要：提出基于第二代自适应Bandelet变换彩色图像融合算法。该算法引入了表现彩色图像灰度正则变化的几何流,对几何规则彩色图像,Bandelet基可以达到最佳逼近,可以很好地获取原始彩色图像的特征信息,为彩色图像融合提供更丰富的信息,特别在处理尖锐的彩色图像过渡时非常有效。通过对256×256的Clock彩色图像仿真实验,实验结果表明算法对于多聚焦、纹理和边缘特征丰富的彩色图像融合是最理想的,无论从主观视觉效果上还是客观质量指标上均优于小波变换的融合算法。The algorithm of colour image fusion based on the second generation adaptive Bandelet transform is presented in this paper.The algorithm introduces geometry flow which describes the regular variation of the colour image gray scale.For symmetrical colour image,Bandelet transform can approach the best approximation and well get the characteristic information of the primary colour image,provides much plenty information for colour image fusion,it is especially effective when processing sharp colour image transition.By simulating 256×256 Clock colour image in experiment,the result reveals that the algorithm proposed is the best fitted one for fusing the colour images with multi-focus,texture and plenty edge characteristics.Furthermore,this algorithm is better than wavelet transform either in subjective visual effects or objective quality index.
